Congradulations! And Welcome to the D24T forum.

The 6 GPs do pull a lot of amps, but verify all the GP feed wires and connections are in good shape. IIRC, I measured around 9VDC on the GP bussbar. Also, these engines do not start well if one or more (esp.) GPs are bad.

Starter must be spinning engine fast for it to light off, especially after an extended dormant period. ~600 RPM? Take care of the starter not to overheat it. 10 sec. crank, 30 sec. rest.

If the injector lines are dry, that requires considerable cranking to get fuel into the injectors. Helpful tip: Hold accelerator at WOT to get more fuel to flow BUT::: Arrange your air intake so someone can quickly cover the intake plenum with a board or other suitable object (NOT a hand, NOT a rag) incase it starts to runaway, a distinct possibility.

Handle the injector hard lines with care, try to let them find their natural position when retightening them, and don't reef on the nuts too hard.

I had one that had sat awhile and just would not start. Lines were bled, spitting diesel, etc. We had to resort to pulling the injectors and squirting 1/4 tsp. in each hole to get the rings to seal. After that, no problems.

OTOH, we just revived another one that sat a couple years with BD in the rainy PNW (hood partially open) and, after checking belts, hoses, filling the cooling system, it started up so fast it startled us!

To start with:

1. Good battery charger on good battery.
2. Loosen the #1 injector line at the injector, crank with key on (to energize the fuel cutoff solenoid), and check for fuel spurting at the opened union.

If not, work backward from there.

Gasoline in the fuel lines could be problematical.

Too much (air) pressure into the IP also not good; you don't want to blow out the seals.

You can force the GPs to glow longer by disconnecting the terminal at the thermostatic sensor at the rear of the head, just under the rear cam pulley. This will fool the GP controller into thinking it is max. cold and to energize the GPs for the max. time.
